To all whom it may concern:

Be it known that I, GEORGE P. A. WVEISEN- BORN, a citizen of the UnitedStates, residing at Seattle, in the county of King and State ofWashington, have invented new and useful Improvements in Churns, ofwhich the following is a specification.

This invention comprehends generally improvements in agitators and moreparticularly has reference to a churn.

It is the primary aim and object of the present invention to provide adevice of the above character designed so that it will continuouslyreciprocate vertically subsequent to the imparting of movement theretoso as to agitate the liquid or material within the receptacle.

It is an equally important object of this invention to provide inconjunction with the reciprocating receptacle a dasher designed to beheld stationary so as to thoroughly agitate and mix the material withinthe receptacle during the reciprocatory movement of the device.

As a further improvement, this invention includes the provision of adevice of the above character wherein an adjustable spider is employedso as to assure of the maintenance of various sized receptacles inosition in a device, and to admit of their being easily and quicklyattached to and removed from their supporting means.

More particularly, this invention contemplates the provision of adeviceof the above mentioned character designed for making ice cream, churningmilk, and in addition being capable of mixing various other liquids ormaterials.

Among the other aims and objects of this invention may be recited theprovision of a device of the above mentioned character with a View tocompactness, and in which the number of parts are few, the constructionsimple and the cost of production low and the efliciency high.

Other improvements and novel details in the construction and arrangementof the various parts of the apparatus will be brought out more in detailin the description to follow, which for a clear understanding of theinvention should be considered in Serial No. 643,465.

connection with the accompanying drawings forming a part hereof, andwherein is disclosed for the purpose of illustration a convenient andsatisfactory embodiment of the invention. It is to be noted in thisconnection that minor changes in the construction and arrangement ofparts may be made without departing from the principle of 0peration ofthe various parts.

The invention is clearly illustrated in the accompanying drawings, inwhich:

Figure 1 is a side elevation of the invention;

Fig. 2 is a vertical section of the invention partly in elevation;

Fig. 3 is a transverse section taken on line 3-'3 of Fig. 1; i

Fig. 4 is a top plan view of the device.

Similar characters of reference are employed in all of the abovedescribed views, to' indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings, there isprovided a bracket indicated in its entirety by the numeral 1 whichconsists generally of an attaching plate 2 from which projects a lateralarm 3, supported with respect to the plate through the instrumentalityof a brace 4. The outer end of the arm is formed with an opening inwhich is fitted a vertically disposed nipple 5 for a purpose that willpresently appear.

Anupper cross piece 6 is now employed and is formed with a centralopening 7. Cooperating with the upper cross piece 6 is a lower cross bar8 while connected to the respective ends of the cross bar are suitableflexible elements such as chains 9, the upper ends of which are engagedin adjacent hook bolts 10, the threaded shanks 11 of which are arrangedthrough one of the arms of the crossv piece 6, and adjustably supportedtherein by means of wing nuts'12. By this arrangement it is apparentthat the distance between the cross piece 6 and the cross bar 7 may bevaried.

In order to assure of a continuous reciprocatory movement of the device,coil springs 13 are employed and have their upper ends connected in thearm 3 and their lower ends engage in U-shaped bolts 14 on one of thearms of the cross piece 6, as indicated. Another coil spring 15 has itsupper end engaged in a U-bolt 16 and cross bar 8, and its lower enddetachably "engaged in a hook 17 which is mounted at a point directlybeneath the bracket 1, as indicated.

As intimated, improved means have been employed for adjustablysupporting a receptacle in a device, and in reducing this feature of theinvention to practice, a spider indicated in its entirety by the numeral18 is employed. Hooks 19 are formed on the opposite ends of one of thecross bars and "are designedi r engagement with any of the op osed linksof the chains, 9' while the other crossarm is formed with flanges 20which are designed to engage the opposite points of a main receptacle 21when the latter isseated on the Spider. Thehooks 19 may bein the form ofprojections to en age in the links of the chain, and they W1 1 be heldagainst displacement by thechains'being drawn taut when the receptacle21 is clamped in place. "These pTOIe CUOhS alSO are so formed that theywill form trunnions upon which the spider can rotate; so that it may betilted when the receptacle. is being put in place. By making the spiderthus rotatable the ease with which the receptacle may be attached orremoved is greatly facilitated.

A secondary receptacle 22 is mounted within the main receptacleand istermed with supporting legs 23 engageable with the bottom of the mainreceptacle. An 11npl'oved cover 2 1 is now employed and is designed forrernovably closing both the receptacles. This cover consists enerally ofa disk 25 formed with a depending annular .concentric portion 26 whichin turn is formed with'a" depending annular flange 'lhis'fian'getelescopes within the secondary receptacle 22 and serves to cooperatewith the under surface of the depending'portion 26 in closing saidsecondary receptacle. The cover is provided with a central opening 28for a purpose that will presently appear.

WVith a view toward providing improved means for cooperating with thesecondary receptacle in assuring of a thorough agi tating of the liquidthereima scraper or dasher indicated in its entirety by the numeral 29is provided andconsists of a plurality of radially arranged blades whichare designed to be vertically disposed within the receptacle 22. Asupporting rod 31 is extended centrally through the "dasher and isengaged at its lower end a nut 32 which serves as a support, whilecooperating with the nut 32 is another nut 33 which bears against theupper edge of the dasher and prevents reciprocatory move- .ment of thedasher; This rod is extended upwardly, and is disposed through theopening 28, being formed with a spiral portion 34 which cooperates withthe correspondingly formed collar 35 which in, turn is formed on theupper surface of the cross piece 6 above the opening 7 therein. Theupper end of the rod .is threaded as at 36 and is disposed through thenipple 5 being capable of partially rotary movement therein while wingnuts 37 are adjustably engaged on the threaded portion 36 and contactwith the upper and lower surfaces of the nipple 5 in assuring of thesupporting of the rod and the dash'er in a stationary position It isappreciated by the construction described that the rod is allowed torotate yet is prevented from vertical movement. 7

The mode of operation of the present invention may be reviewed asfollow'sz'Assumihg that the parts have been assembled in the mannerdescr.ibed,and as illustrated in the drawings, upon moving the crosspiece 6 against the tension of either of the sprmgs 13 and 15 andreleasing the cross piece one of the springs will contract while theother exoandsg'and this operation will be continuous until the springsbecome counterbalanced; yet it is appar'ent'beit'o're this occursanother movement may be imparted to the cross piece 6. During thisvertical reciprocatory movement of the receptacle 22, the dasher 30which is held in stationary position will agitate the material withinthe receptacle 22' and by reason of the fact'tli'itthe internally spiralcollar 38 reciprocates with the receptacle and engages the spiralportion 34 the rod and consequently the "daslier 30 will be alternatelyrotated in different directions and will assure the scra mg of the sidesof the receptacle and in addition agitate the liquid therein. Thisscraping of the sides of the receptacle is especially desirable when icecream is be ing made in the device. It is of course apparent that whenice cream is being made that cracked ice is placed in the receptacle 21and about 'the outer sides of the receptacle 22 to' assure of thefreezing action. Of course whenbutter is beingchurned or other liquidsbeing agitated, it is'unnecessary to place ice in the receptacle 21. Toadjust the relation of parts and to accommodate a smaller receptaclethespider 18 is detached from certain of the opposed links and "engaged inother opposed links nearer to the cross niece/6 whereupon the receptacleis placed in position above the spider while the wing nuts 12 arefinally adjusted to clamp the cross piece against the top of thereceptacle and in this mannerhold the receptacle against displacement;making the spider -18 rotatable between the chains 9 it may be tilted tofirst receive the bottom of the receptacle 21 after which the top isthen swung into position beneath the cross piece 6 and is then clampedin place by turning the nuts 12. This not only facilitates putting thereceptacle 21. in place, but it will require a minimum adjustment of thenuts 12 for clamping it.

It is believed in View of the foregoing description that a furtherdetailed description of the operation of the invention is entirelyunnecessary. Likewise, it thought that the advantages of the inventionwill be readilv apparent.

As many changes could be made in the above construction and manyapparently widely difl'erent embodiments of this invention could be madewithout departing from the scope thereof, and it is intended that allmatter contained in the above descriptio'i or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitedsense.
